I can, therefore I am.

What you do today can improve all your tomorrows.

If you're going through hell, keep going.

You never know what motivates you.

Either you run the day or the day runs you.

Always desire to learn something useful.

Go for it now. The future is promised to no one.

If you think you can do it, you can.

Be thine own palace, or the world's thy jail.
